---- ****** Using 2.3.3 rooted firmware ****** ----

As per jpmwright http://xdaforums.com/showpost.php?p=16281837&postcount=126

I found that I couldn't use xRecovery on my phone with Docomo firmware. So you may need to reflash your phone for 2.1 firmware and re-root it.

So sync/backup all the data you want from your current rooted phone including any Docomo specific apps, for apps I recommend using Titanium backup from the Market.

Follow the guide here to get back to a generic 2.1 firmware: http://xdaforums.com/showthread.php?t=920746

I used "FlashTool version 0.2.8" and "X10i Generic version 2.1update1 build 2.1.A.0.435"

You should now be on 2.1 generic firmware with root.

Now to get to X10i 2.3.3 rooted firmware follow: http://xdaforums.com/showthread.php?t=1192152

After you have completed your phone will be a X10i 2.3.3 rooted phone with generic setting, so for your APN settings use the info from post 1.

(BTW for NTT Docomo, voicemail access number is 1417, vm off is 1470, vm on is 1471)

So now you can use your phone, but you will no longer have access to Docomo Market nor SO-1B apps.

To gain access again, you will have to modify build.prop using FlashTool, Root Explorer or other tools, the file location of build.prop is in flash at /system/build.prop

I noticed this time I had to modify more occurance of build.prop in order for it work or Docomo Market or Market.

Docomo Market does not look at the ro.build.fingerprint properties, but is needed for Android Market.

ro.build.fingerprint, you may wish to comment out the current value with a #

so you can swith between the two identity.

my build.prop modification below:

ro.semc.product.model=SO-01B

ro.build.product=SO-01B

ro.product.name=SO-01B_1241-1846

ro.product.device=SO-01B

ro.build.fingerprint=docomo/SO-01B_1233-7397/SO-01B/es209ra:2.1-update1/2.01.B.0.19/ExBC:user/release-keys

ro.product.model=SO-01B

ro.semc.product.name=SO-01B

ro.semc.product.device=SO-01B

ro.product.brand=docomo

If you want Mixi plugin for Timescape you can get it from Market:

** 2.01.b.0.19 Docomo firmware is out i.e. Dual touch**

** Root with Flashtool 0.2.4 **

** Legacy info, you can now just use Docomo's official 2.1 firmware and then root **

** To go back to Docomo firmware use values 1233-7397 for *.prop files **

Nordic 2.1 on SO-01B.

The only method I managed to get my Jailbroken 1.6 UK Generic firmware SO-01B updated to 121. Nordic was to use the method from http://xdaforums.com/showthread.php?t=825201

Phone rooted fine with http://xdaforums.com/showthread.php?t=824788

Do use the "Backup and restore" app, so you can restore your APN settings, alot of the other settings didn't restore which was a bit of a shame. (e.g. google/twitter account etc.)

"Official" Docomo Market from 1.5 firmware fails to work, obviously due to new browser user agent ID.
